There is a wealth of material that refutes that claim out of hand. Josh McDowell, Lee Strobel and William Ramsey, among many others, have all shown how preposterous that claim is.

Pray that the Lord Jesus will reveal himself to the unbelievers who promote this stuff. When one or two of them get saved it will be a great testimony to the power of Jesus Christ. Atheists make great Christians when they get saved because they understand why they believe what they believe.

Someone very close to me, who is very much into occult , has said for years that the Bible is nothing but a bunch of fables.

But what does The WORD of TRUTH say? It is the unbelieving who's allowed themselves to believe deceptions that are based on fables. So God says they've been turned unto fables,(because they wouldn't endure sound doctrine) yet they say that the Bible is a bunch of fables....Hummmm, who to believe? People used by and under the control of Satan, or Jesus Christ, who has already defeated Satan at Calvary?

"For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;

And they shall turn away their ears from the truth, and shall be turned unto fables." II Tim.4:3-4

"For by grace are ye saved through faith; and that not of yourselves: it is the gift of God."
